That was an issue with the language Loglan where the author claimed copyright on the language. As a reaction the community created Lojban. Basically GNU/Lojban.
Whether you really can copyright a language is pretty dubious though, probably not. In the case of Loglan it was not enforceable but Lojban is now far more popular anyway, so it is moot.
As for Toki Pona in practice it is not much of an issue because the free learning material is good enough. The language is very small and not that strictly defined anyway but I get your concern.
